The most recent classification of WHO for endocrine tumors (2022) includes seven different subtypes of PIT1 lineage tumors which can variably express GH and can also be associated with acromegaly, namely, DG and SG somatotroph, mixed lactotroph‐somatotroph, mammosomatotroph, acidophil stem cell, mature plurihormonal PIT1‐lineage, and immature PIT1‐lineage adenomas [11]. The gene discussed is GH1; the disease is adenoma.
